G. W. LOVELL BASE AND TOP GUIDE FOR SUBMERSIBLE WATER PUMPS Filed Aug. 17, 1955 INVENT OR 6945097 144 LOVELL 5 ATTORNEY United States Patent BASE AND TOP GUIDEYFOR SUBMERSIBLE WATER PUMPS Gilbert W; Lovell, Nashville, Tenn. Application August 17, 1955, Serial No. 529,027

1 Claim. 01. 103-219 This invention relates to a base and top guide for submersible water pumps, and has for one of its objects the production of a simple and efficient means for supporting a submersible water pump in a deep well, and also for holding the pump in the center of the well so that plastic pipe may be safely used in the installation thereof.

A further object of this invention is the production of a simple and efiicient base for supporting a pump in a central location in a deep well so as to carry the weight thereof and thereby relieve strain from the plastic pipe which is attached to the pump.

Other objects and advantages of the present invention will appear throughout the following specification and claim.

In the drawing:

Figure 1 is a side elevational view of the pump, the support and the guide showing the same positioned in a well, certain parts of the support being shown in section;

Figure 2 is an enlarged side elevational view of the support;

Figure 3 is a top plan view of the top guide;

Figure 4 is a top plan view of the socket member, a portion of the pump being shown in section.

By referring to the drawing in detail, it will be seen that designates a rigid pump support which comprises a base 11 which is adapted to rest upon the bottom of the Well W. The base 11 preferably comprises a steel plate spur 12 which carries an upright pipe coupling or in ternally threaded socket member 13 into which is threaded the lower threaded end of the pipe standard 14. This pipe standard 14 is preferably galvanized pipe, and may be of any selected length. The steel plate spur 12 is of the conventional type and is adapted to hold the torque out of the submersible pump when the pump starts.

The pipe standard 14 is provided with an upper threaded end 15 which fits in the depending threaded collar 16 of the bell type socket member 17 of the pump support. This socket member 17 is adapted to receive the lower end of the pump -P which pump is of the conventional type. The upper edge 18 of the socket member 17 is preferably inclined toward one side thereof, to facilitate the fitting of the bottom of the pump into the socket member 17 during the assembly process. A set screw 19 is carried by the socket member 17 for engagement with the bottom of the pump to hold the pump P from being accidentally disconnected from the support. Water entrance apertures 17 are formed in the bottom of the socket member to permit flow of water to the pump P.

A top guiding disc or top guide 20, fits over the neck 21 of the pump P, and is preferable about one inch less in diameter than the well W. The neck 21 passes through the central aperture 22 formed in the top guiding disc 20. The disc is also provided with a wire receiving aperture 23 through which the conventional control wires 24 pass leading to the pump P. This disc 20 holds the pump in spaced relation relative to the side of the Well and prevents the pump P from lying over against the side of the well and possibly mashing the insulation on the ice Patented Sept. 30, 1958 wires 24. The top guide 20 preferably comprises a rubher of resilient plate.

It should be understood that the present device in the nature of a pump support is adapted to fit in the bottom of a well below the surface of the surrounding ground. *It is verydiflicult matter to anchor the bottom end of a pump upon a support without employing some auxiliary guiding or directing means to place the bottom end of a pump upon a support. Consequently, the inclined upper end 18 of the socket member 17 is of great importance due to the fact that the bottom end of a conventional pump may be dropped upon the upper inclined edge 18 of the socket member 17, and as the bottom end of the pump strikes this upper inclined edge of the socket member near its high side, gravity pull upon the weight of the pump will cause the bottom of the pump to slide downwardly over the inclined edge of the socket member and to thereby automatically drop into the socket member as the central axis of the pump approximately registers with the central axis of the socket member without the necessity for employing auxiliary pump support locating means;

It should be understood that the set screw 19 may be used to anchor the pump and the socket member together should the pump and socket member be lowered into the well simultaneously. Where plastic pipe is used the pump support may be placed within the bottom of the well and the pump may be dropped into engagement with the socket member in a manner as described above. Even when the pump and socket member are assembled above ground, it is important that the upper inclined edge 18 be provided in order that the pump may easily be guided into fitting relation within the socket member, since the bottom end of the pump will contact the upper inclined edge 18 and the weight of the pump through the force of gravity will cause the bottom end of the pump to automatically slide down the inclined edge 18 from the hightoward the low side, and when the central axis of the pump approximately registers with the central axis of the socket member, the bottom end of the pump will automatically drop into the socket member.

The present structure permits the use of plastic pipe 22 on submersible water pumps in deep wells. Heretofore all submersible pumps used in deep wells were suspended on the drop pipe from the top of the well. Due to the chemical action of certain minerals in the water upon metal pipe which causes the pipe to corrode, the use of plastic pipe 22 provides a great advantage, since the plastic pipe 22 will not corrode. However, when plastic pipe 22 is used, the pump must be supported by some other means than the drop pipe, and hence the importance of the present invention wherein the entire weight of the pump and pipe is carried by the pump support 10 which rests upon the bottom of the well W. Any desired length of pipe may be installed between the socket 17 and the base 11. The top guiding disc fits loosely within the well W and holds the pump centrally therein and prevents the wires 24 from coming into contact with the wall of the well and being injured by being pressed against the wall of the well.

It should be understood that certain detail changes in the construction of the invention may be employed without departing from the spirit thereof, so long as such changes fall within the scope of the appended claim.

Having described the invention, What I claim as new is:

As a new article of manufacture, a rigid pump support adapted to fit in the bottom of a well below the surface of the surrounding ground, said pump support having a base adapted to rest upon the bottom of a well, a standard carried by said base and adapted to be supported in a substantially vertical position within a well, a bell type socket member carried by the upper end of said standard for receiving the lower end of a conventional pump to anchor the bottom end of a pump within the bottom of a well against lateral displacement from said pump support, the rigid pump support being. adapted to carry the entire weight of a pump relative the weight of the pump from the drop pipe thereof, theupper edge of said bell ty-pe socket member being inclined toward one side thereof to provide a guide to direct the bottom end of a conventional pump into said socket member as the bottom end of the pump strikes the upper inclined edge of the socket member near its high side, gravity pull upon the weight of the pump causing the bottom of the pump to slide downwardly over the inclined edge of said socket 4 member and to thereby automatically drop into said socket member as the central axis of the pump approximately registers with the central axis of said socket member without the necessity of employing auxiliary pump support locating means.
